Holy Communion is the highlight of our day, our week, our life; why not linger awhile to enjoy the intimate presence of God Himself?
When you are given a gift, you are expected to write a thank-you note, or at least to say "thank you" to the giver in person. If this is what you are expected to do, having received something that is merely material, and therefore passing, is it not much more important to pause and give thanks when our Lord has given us Himself?
If you recived a guest into your home, you would set aside chores and other activities and spend time with your guest. Why not, then, take a few minutes to entertain our Lord Jesus, having received him in your soul?
